This invention relates to a high lift valve primarlly for automatic temperature control. I

It is particularly aimed to provide such a valve as will give gradual control of heating or cooling systems, and to provide means whereby a cylinder air motor or other diaphragm valve has suiilcient travel to fully open .or clou the valve.

Figure 2 is an enlarged view primarily taken on the line 2-2 of'Figure 1;

Figure 3 is a' horizontal section taken on the line 3-3 of Figure 2;

Figure 4 m an elevation of the valve sleeve or cage; and

Figure 5 is another elevation of said sleeve or cage taken 180 degreeswith respect to Figure 4.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, i0 designates a cast or other valve body having an inlet i l and an outlet at I! for a heat n medium or a cooling medium, said inlet and outlet preferably being screw threaded for connection of pipes or conduits thereto as suggested in dotted lines. The bottom or the body is closed by a plug in the form of a nut it screw threaded into the same at I4 and having a ground conical seat at i5.

Press fitted into the body II as shown is a sleeve or cage it which has ports il in line with the inlet ll whose combined area is approximately twenty percent greater than the area of the inlet l2, and such ports may be drilled on an angle for progressive opening and closing. It

will be particularly noted that the inlet ii widens at is toward the ports ll.

Rotatable and slidable within the sleeve .or cage 16 is apiston is whose lower edge is beveled to the same angle as that of the cone is and such edge III, as wellas the cone Ii are neck II at the top whereby a cylindrical housing 22 is attached thereto. At the top, a pipe or' copper tubing 23 leads to the cap 24 on said cylinder and it serves as an air connection. A cylindrical motor 25 is vertically movable in the housing 22 and such housing adjacent the bottom and in an inclined wall 26 is provided with openings or perforations to allow for air circulation and adjustment of valve stem connections. This cylinder motor 25 is the same as that disclosed in my co-pending application, Serial Number 492,099. I

A stem '28. is detachahly screw threaded at 29 to the base of the motor and it depends there from and slidably-through the upper end of the sleeve it, with standard valve stem packing means 29 mounted in such upper end of the sleeve and surrounding the stem 28 in fluid-tight relation. such stem 28 at its lower .end has a swivel connection at 30 such as the standard valve stem and disc connection, with the piston is, to permit the valve is to both slide and rotate without binding, although with an accurate fit, so that there will be a seal between inlet side and outlet side of the valve.

It will be realizedthat the parts 22 and 26 may be made of anysuitable material, for inground to form an intimate and tight ioint. 'I'hestance, metal, rubber, or the like.

In operation, the piston valve is will be cperated by the motor 25 and various efllcient currents for its movement within the sleeve it will fully open and close all ports. The cooling medium or heating medium will enter through the inlet H, expanding at i8, passing through the ports it, through the sleeve i6, and from the latter through a port 3| in line with the outlet l2. As previously stated, the engagement between the surface 20 .and cone surface 15 is a ground joint so that a seal will be produced Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:

A structure of the class described including a valve body having an inlet and an outlet, a sleeve in said body, said inlet being widened at the sleeve to'enable expansion of the fluid passing therethrough, said sleeve in line with vthe wide portion of the inlet having ports of. an overall area in excess of the normal area of the inlet,

- said sleeve also being ported for communication SQIQSIEGVBOIMG llhssascrewthreadedwith the outlet, a piston slidable in the sleeve, and said sleeve beingof a size to enable said piston to fully open and close said ports, means to actuate the piston, a plug inzsaid .body, and a ground jointon an inclined surface between said piston and said plug.
